After weeks of intense criticism over the White House handling of security for the Benghazi consulate before, during, and after the terrorist attack that killed four Americans, including Ambassador J. Christopher Stevens, the Senate will begin holding hearings in less than two weeks to get answers on all of these questions.  The House has already begun an investigation through the Oversight Committee, but the State Department has refused to fully cooperate with either — at least until now.  For the first time, State has agreed to allow Senators to view diplomatic cables and other documents related to the failures surrounding the Benghazi incident, for a limited time.
